6. COMMISSIONING
6.1 Electrical Connections
To improve immunity to the possible noise radiated towards other appliances it is recommended to use a separate electrical duct to supply the
product.
The line voltage may change when the electropump is started. The line voltage may undergo variations depending on other
devices connected to it and on the quality of the line.
Make sure that the mains voltage is the same as that on the motor data plate.
Strictly observe the wiring diagrams below:
- L-N-Earth, single-phase version
- U-V-W-Earth, three-phase version
It is recommended to carry out installation as indicated in the manual, in compliance with the laws, directives and standards in force in the place
of use and depending on the application.
The product contains an inverter inside which there are continuous voltages and currents with high-frequency components.
The differential switch for protecting the system must be correctly sized according to the characteristics indicated in Table 2 and Table 3.
